Model Predictive Control Toolbox

Calculates the singular values of a varying matrix, for example, the frequency response generated by mod2frsp.

Syntax

• [sigma,omega] = svdfrsp(vmat) 
  

Description
vmat is a varying matrix which contains the sampled values F(₁), ... , F(N) of a matrix function F().

If the smaller dimension of F(i) is m, and if 1(i), . . . , m(i) are the singular values of F(i), in decreasing magnitude, then the output sigma is a matrix of singular values arranged as follows:

The output omega is a column vector containing the frequencies ₁ , . . . , N.

Example
See mod2frsp, varying format for an example of the use of this function.
